    Ask Tii - What is the best way to unlock an iPhone

    Hi Rob,

    What is the best way to unlock my iPhone 4 before I sell it.

    I have version 4.3.3

    Regards,

    Quentin

     

    Hi Quentin,

     

    First don't pay someone to unlock it - Key reason - is many of those sites you see banners for to unlock - they will rip you off.  I have had lots of complaints about these vultures in the past.  There is a free app in Cydia to unlock your iPhone - it is called ultrasn0w.  And did I mention it is a FREE app. 

     
    According to the dev team it will unlock iPhone 3G and 3GS' with the following base bands -  04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00.   
    it will also unlock iPhone 4 with baseband 1.59.00 
     
    To figure out your base band open the settings app - go to "General" then to "About" then scroll down to the "Modem Firmware".  As an example my iPhone 4 is at 4.10.01 - so it can not be unlocked.  
     
    Just to clarify - Unlocking means you free up the phone to work on another carrier.  Jailbreaking means you free up the phone to install apps not authorized by Apple - and to unlock - you need to be jailbroken - and then in Cydia - go to the app ultrasn0w - and if you have the right baseband for your phone - just run that app and you will be unlocked.  
     
    Let me know if you have any questions per the above. 
     
    Regards,
     
    Rob W
